Hey Jeff, thanks.
Yeah, I can render trailer information when using your examples but *only* if I disable signing my tags. Here's what my global Git configuration looks like:
[tag]
gpgSign = true
sort = version:refname
...and here's a better example to demonstrate:
mkdir demo
cd demo
git init
touch one.txt
git add .
git commit --message "Added one"
git tag 0.0.0 --message "Version 0.0.0" --trailer A:0
touch two.txt
git add .
git commit --message "Added two"
git tag 0.0.1 --message "Version 0.0.1" --no-sign --trailer A:1
Notice how Version 0.0.0 creates a signed tag but Version 0.0.1 forces the tag to not be signed. I can then run the following:
git tag --list \
--format="%(refname:short)|%(taggerdate:short)|%(taggername)|%(subject)|%(trailers:key=A)" \
| column -s "|" -t
...to produce this output:
0.0.0 2024-09-06 Brooke Kuhlmann Version 0.0.0
0.0.1 2024-09-06 Brooke Kuhlmann Version 0.0.1 A: 1
So I can see that Git tag trailers are working but only if my tags are *not* signed. Here's what each tag looks like when I cat them out:
git cat-file tag 0.0.0
object ad13b82ff41d5698cfb03a06b95e6e5a98386ed4
type commit
tag 0.0.0

So it seems like signing my tags is causing trailer information to be lost?
